I have a 2012 Coachmen Chaparral. The original battery finally died. Can I upgrade to an AGM battery? Any other changes need to be made? Or is just “Plug N Play”?

You can change to an AMG. However, as others have written...

“AGM batteries are designed to be charged at a low rate and slowly. Unless your converter/charger can tell difference between an AGM and flooded battery it will charge the AGM like it's a flooded battery, which will work but it also will shorten the life of the battery.”

The only thing I know about them is overcharging kills them.

AGM is still a lead acid battery so no need to change your charging system. BTW you will not be upgrading by switching to the AGM as it won't last 8 years.

8 years is fantastic life !

Upgrading depends on the converter charger you have. Likely it is a WFCO. Upgarding to a Progressive Dynamics with Charge Wizard will guarantee the maximum life of your new battery.

For best answers post your converter model number and the specific battery you intend to use.

I agree, as I upgraded to "Progressive Dynamics with Charge Wizard" as I lost 2 batteries with short life. Happy so far. I did add a cheap (China) monitor with a shunt to check voltages and amps.

As long as it is "reasonably" accurate, then it is worth what you paid for it. !

I have a Cabelas AGM ,bought in June of 2012, still going . Have always charged it back up as soon as I was done with it. I can still get about 5 hours out of on my one man inflatable pontoon boat fishing.

Might want to consider a change to Lithium batteries... expensive, but, long term costs re generally lower, and features and advantages may outweigh initial cost. LifeBlue has a version which can be charged down to -4 degrees - typically, Li batteries can't be recharged below 32 degrees...
